The video tutorial explains the circulation in Earth's atmosphere, focusing on wind formation, the role of convection cells, and the Coriolis effect. It covers how air pressure, temperature, and density affect wind strength and direction. The tutorial also describes different types of winds, such as polar easterlies and trade winds, and explores the concept of convection cells in detail. An imaginary scenario of Earth without rotation is discussed to illustrate the impact of the Coriolis effect on wind patterns.
